SPECIFICATION forming part of Letters Patent No. 458,679, datedSeptember 1, 1891.

Application filed April 10, 1891. Serial No. 388,348. (No model.) I

To all whom it may concern:

Be it known that we, WILLIAM N. BEARDS- LEY and ALVIN D. MoULToN,citizens of the United States, and residents of Bridgeport, in thecounty of Fairfield and State of Connecticut, have invented certain newand useful Improvements in Oartridge-Orimpers, of which the following isa specification.

Our invention relates to an improved crim ping-tool for papercartridges. The hardened glazed surface of a paper shell is broken bythe operation of crimping, which consists in turning inward the mouthand folding such turned-over portion upon the interior cylindricalsurface of such shell. This crimping process destroys the texture of thepaper, so that the turned-over portion is rendered soft and pliable, andconsequently will not lie down firmly upon the interior of the shell.This pliable condition also greatly weakens its power of resistanceagainst the explosive gases, especially since the introduction of nitroand other smokeless powders.

The object of our invention is to restore the turned-over end or mouthof the shell to its former degree of hardness, and thus greatly increaseits power of resistance, besides improving the appearance of the shellafter the crimping process.

To this end our invention consists of a combined fiexible shell followerand ironer employed in conjunction with the crimping mechanism to followdown the crimped mouth of the shell, ironing such crimped portion firmlyagainst the cylindrical interior through the combined means of therotating motion and frictional contact of such ironer with the crimpedportion.

It also consists in the detail construction and arrangement of theparts, all as hereinafter more fully described, and particularly pointedout in the claims.

To more fully understand our invention reference is had to theaccompanying drawings, and to the figures of reference formed thereon,which drawings also form a part of this specification.

Figure 1 represents a side elevation and broken view of an ordinarycrimping-frame, closer-head, broken sectional view of a shell, andsectional view of the closer-head with our improved follower and ironertherein. Fig. 2 represents a side elevation of the crimping-head, alsosection of the frame and handle through line X of Fig. 1. Fig.3represents a front elevation of the crimpinghead. Figs. 4, 5, 6, 7, 8,9, 10, ll, 12, 13, 14, and 15 represent detail views.

Itsconstruction and mode of operation areas follows:

1 1 represent the combined follower and ironer in two parts or sections;2, a spiral spring exerting an outward pressure on thefollower-sections; 3, follower-holder, to which handle 4 is attached,said holder having a cylindrical bore and being journaled in the bearing5 of the frame (3; 7, crimping-head; 8, crimping-pins situatedtransversely therein.

The ironing-follower ispreferably composed of two hemispherical tubularsections 1 1. The spring 2 is so arranged between such sections that itsforce is exerted outward, so that said sections are opposed to eachother and are placed within the cylindrical bore 9 (see Fig. 1) of theholder and arranged to have a free longitudinal movement therein. Theyare also made, preferably, of smaller diameter than the cylindrical bore9, (see end elevation of the follower-holder, Fig. eh) thus providingroom for their expansion. The pins 10, situated transversely in theholder 3, each engage a slot provided in sections 1 1, as seen at 11,Fig. 5, which represents a detached plan view of one of the sections.These slots, in connection with pins 10, retain the follower-sections inthe holder, and also place them under the control of such holder 3 inits rotative action. The spring 2 (see Fig. 0, which represents an endelevation of the lower section of the follower) is mounted upon stud 12,which stud projects from section 1 and operates to keep spring 2 inplace.

Fig. 7 represents an end elevation of both sections of the follower.

The crimping-head 7 (see Fig. 8, which isa sectional side elevationthrough a of Fig. 3)

has a part of its interior threaded and is mounted on the threadedportion 13 of holder 3, (see also Figs. 1 and 9,) thus placing bearing 5of frame (3 between such crimping-head and shouldered portion 14 ofholder 3. The four crimping-pins 8 are held in the head 7 by means ofscrews 15. lVhen ready to crimp a shell, the follower-sections areforced back into the holder 3, with the ends of such sections projectingoutward therefrom a little in advance of the crimping-pins, as seen inFig. 10, (which represents a section of a shell and section of followerthrough line as of Fig. 9, also a detached view of the crimping-pins.)As shown in this view, the end or mouth of shell 16 is brought againstthe annular groove 17 of such pins. The ends of the crimping-pins willlimit the expansion of the follower-sections 3, such ends being soplaced with reference to the internal diameter of the shell 16 that thefollower-sections will readily enter the mouth of such shell, as shownin Fig. 10. The crimping-pins, under the rotating movement of thecrimping-head and the longitudinal pressure exerted by means of handle18 (see Fig. 1) through rod 19 and pad 20, will turn the end or mouth ofthe shell inward, (as seen in Fig. 11, which view is similar to Fig.10,) and such turnedin portion, instantly engaging the followersections3, will compress the same against the outward influence ofsection-spring 2, and as such crimped portion 16 is forced down theinterior of the shell it will, by its engagement with thefollower-sections, carry such sections with it. The rotating motion ofthe crimping-head will also revolve the follower sections against thecrimped portion 16 of the shell and by means of the frictional contactof such sections therewith through the medium of spring 2 will exert aforce suflicient to burnish and hardensuch crimped portion, forcing thesame down firmly upon the interior of the shell, and by means of thisironing process restore such crimped portion to its original degree ofhardness, also increasing its power to resist the expanding gases. Thecrimped end will be continued down to the wad, (see Fig. 12, which is abroken sectional view of the shell, side elevation of thefollower-sections and follower-holder, also detached view of thecrimping-pins, Fig. 13 being a similar view of the shell, showing thecrimped end folded in and one of the crimping-pins engaged with the endof the shell,) the end of the follower being so formed that it will notdeface the center of the wad by contact therewith. The crimping-pins 8are so constructed that they can be reversed (see Fig. 14) in theirposition in the crimping-head, using the straight portion of such pins,when necessary, to form the square end 21, instead of a round end, asshown in the other views.

The device is shown attached to an ordlnary crimping-frame and themotive power for revolving the crimping-head applied to the crank orhandle 4:.

As the only feature of our invention is embodied in the crimping-head,it is quite evident that the follower-holder 3 could be furnished withthe shank 22 (see Fig. 15) and such shank used in a chuck revolved by acontinuous power, as a lathe, or in any other suitable manner, usingsuitable means whereby the necessary pressure is needed to force theshell against the crimping-pins.

lVe employ the two hemispherical tubular sections, as shown, they beinglighter and less expensive than two solid hemispherical sections wouldbe. The gist of our invention lies in the expansible feature of the twosections, so that they may be caused to expand and thus exert an outwardforce against the crimped portion of the shell, ironing such crimpedportion down upon the UlICLlDlDGCl portion as fast as such crimpedportion is presented.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is
